120 - EM_SETTYPOGRAPHYOPTIONS 3.0
121 + EM_SETUNDOLIMIT 2.0

142 - WM_STYLECHANGED (things like read-only flag)
147 * EN_CHANGE (sent from the wrong place)
164 * EN_UPDATE (sent from the wrong place)

173 - ES_EX_NOCALLOLEINIT
175 - ES_MULTILINE (currently single line controls aren't supported)
177 - ES_READONLY (I'm not sure if beeping is the proper behaviour)
183 - ES_WANTRETURN (don't know how to do WM_GETDLGCODE part)
190 * RICHED20 TODO (incomplete):
192 * - messages/styles/notifications listed above
194 * - add remaining CHARFORMAT/PARAFORMAT fields
195 * - right/center align should strip spaces from the beginning
196 * - pictures/OLE objects (not just smiling faces that lack API support ;-) )
197 * - COM interface (looks like a major pain in the TODO list)
198 * - calculate heights of pictures (half-done)
199 * - horizontal scrolling (not even started)
200 * - hysteresis during wrapping (related to scrollbars appearing/disappearing)
202 * - how to implement EM_FORMATRANGE and EM_DISPLAYBAND ? (Mission Impossible)
203 * - italic caret with italic fonts
205 * - most notifications aren't sent at all (the most important ones are)
206 * - when should EN_SELCHANGE be sent after text change ? (before/after EN_UPDATE?)
207 * - WM_SETTEXT may use wrong style (but I'm 80% sure it's OK)
208 * - EM_GETCHARFORMAT with SCF_SELECTION may not behave 100% like in original (but very close)
209 * - full justification
212 * - ListBox & ComboBox not implemented
214 * Bugs that are probably fixed, but not so easy to verify:
215 * - EN_UPDATE/EN_CHANGE are handled very incorrectly (should be OK now)
216 * - undo for ME_JoinParagraphs doesn't store paragraph format ? (it does)
217 * - check/fix artificial EOL logic (bCursorAtEnd, hardly logical)
218 * - caret shouldn't be displayed when selection isn't empty
219 * - check refcounting in style management functions (looks perfect now, but no bugs is suspicious)
220 * - undo for setting default format (done, might be buggy)
221 * - styles might be not released properly (looks like they work like charm, but who knows?
